3Com Network
Director Service
Levels
3Com Network Director uses the service levels on the devices it
configures as shown in Table 104
.
Table 104 Service Levels Used by 3Com Network Director
The classifiers created by 3Com Network Director are mapped to these
service levels as follows:
■ Classifiers created for NBX traffic are mapped to the Voice service
level.
■ Classifiers created for applications or servers that have been selected
for prioritization are mapped to the Business Critical service level.
■ Classifiers created for applications or servers that have been selected
for blocking are mapped to the Drop service level.
■ All other traffic is left unclassified and is treated with the Default
service level. This service level does not perform any remarking and
sends all packets to queue 0 (Low).
